* c-common.c(c_common_nodes_and_builtins): Since variants of
void_type_node get built before it is given a name, we need to
give those variants the name, too.
(complete_array_type): We need to work with the canonical main
type of the array, from which we will build the qualified version.
* params.def (PARAM_VERIFY_CANONICAL_TYPES): New.
* print-tree.c (print_node): Display canonical type information
for each type.
* stor-layout.c (layout_type): When we don't know the
alignment of a type for which we're building an array, we end up
guessing wrong, so make the type require structural equality.
* tree.c (make_node_stat): When we build a new type, it is its
own canonical type.
(build_type_attribute_qual_variant): When building an attribute
variant, its canonical type is the non-attribute variant. However,
if the attributes are target-dependent and they differ, we need to
use structural equality checks for this type.
(build_qualified_type): A qualified type is not equivalent to its
unqualified variant; set the canonical type appropriately.
(build_distinct_type_copy): When building a distinct type from
another type, the new type is its own canonical type.
(build_variant_type_copy): When building a new type variant, we
assume that it is equivalent to the original type.
(build_pointer_type_for_mode): When building a pointer type, also
build a canonical type pointer.
(build_reference_type_for_mode): When building a reference type,
also build a canonical type reference.
(build_index_type): When we can't hash an index type (e.g.,
because its maximum value is negative), the index type requires
structural equality tests.
(build_array_type): Build the canonical form of an array type.

because they contain default arguments, attributes, etc.

(comptypes): Use canonical type information to perform fast type
comparison. When VERIFY_CANONICAL_TYPES, verify that the
canonical type comparison returns the same results as we would see
from the current, structural check. Support COMPARE_STRUCTURAL
when we need structural checks.
* decl.c (typename_compare): Fix comment.
(build_typename_type): TYPENAME_TYPE nodes require structural
equality checks, because they resolve different based on the
current class type.
(make_unbound_class_template): UNBOUND_CLASS_TEMPLATE nodes
require structural equality checks (for now).
(build_ptrmemfunc_type): Build the canonical pointer to member
function type.
(compute_array_index_type): Whenever we build a new index type
to represent the size of an array in a template, we need to mark
this index type as requiring structural equality. This goes for
arrays with value-dependent sizes with the current ABI, or all
arrays with ABI-1.

type, use the hash table of array types and build canonical array
types as necessary.

use structural equality (for now).

(lookup_template_class): When we have named the primary template
type, set the canonical type for our template class to the primary
template type. If any of the template arguments need structural
equality checks, the template class needs structural equality
checks.
(tsubst): When reducing the level of a template template
parameter, we require structural equality tests for the resulting
parameter because its template parameters have not had their types
canonicalized. When reducing a template type parameter, find the
